Industrial accelerometers, 4-20mA transmitters and loop powered vibration sensors and systems for use in furnaces, mills, presses and specialised metals production machinery.


As commercial and technical pressures on the production of iron, steel and other metals continue to increase across the globe, the need for more effective plant with 100% availability is becoming an ever higher priority.

At Hansford Sensors we manufacture a full range of vibration sensors to help your business meet the challenges of monitoring and maintaining a wide range of plant and machinery, including furnaces, rolling mills, presses and specialised production machines, plus gearboxes, pumps and fans.

Selecting the best accelerometer or vibration sensor for metals processing depends on a number of factors.  These include:

  • Availability of the plant
  • Cost of breakdown
  • Criticality of the machine/impact on the production process
  • Access to machine, guarding, health and safety implications
  • Environmental factors

We can provide solutions for both online and offline monitoring, with all our industrial accelerometers being designed for use in the toughest environments, including hazardous areas.


Our range of vibration monitoring products includes tough and reliable AC sensors (HS-100 Series) that can be used with local switch or connection boxes (HS-SE), to allow data to be collected via handheld devices.  Alternatively, our 4-20mA accelerometers (HS-420 Series) are designed to be permanently connected to PLCs (programmable logic controllers) for continuous data logging and real time trend analysis.

We also offer advanced systems for monitoring velocity and bearing conditions. These combine AC sensors connected via a vibration module (HS-500 Series) for optimum machine protection. Data readings can be displayed and alarmed both locally and connected back to a PLC for higher level system integration.

For a more advanced analytical online system we have a global network of international partners who can provide complete solutions; contact our sales team for more information.

For low speed applications, with slowly rotating machinery, we offer the option of our specially modified low frequency response accelerometer (HS-100F Series), or a higher sensitivity option of our AC range of sensors.

We also provide a full range of mounting and connection methods, including armoured cables, silicon and fire retardant styles.

Typical solutions include:

Smelting of metal

  • HS-100 Series general purpose 100mV/g AC vibration sensors
  • HS-420 4-20mA vibration transmitters for remote data monitoring
  • HS-100F low frequency sensor for slow rotating machinery
  • HS-500 vibration modules for local display and alarm function
  • HS-SE local switch and connection boxes
  • HS-100I intrinsically safe accelerometers


We have a global network of sales partners, backed by the resources of our central product design, manufacturing and customer centre in the UK.  Our sales partners include vibration analysts, consultants and system builders and integrators.  Each is fully trained, experienced in meeting the challenges of vibration monitoring in a wide range of industrial applications and capable of providing dedicated local technical, engineering and customer service, wherever you are in the world.
